這個程式模擬兩個選手A和B 的某種競技比賽
程式執行需要A和B的能力值（0-1）
請輸入選手A的能力值（0-1）：0.45
請輸入選手B的能力值（0-1）：0.5
請輸入模擬比賽的場次：1000
競技分析開始，共模擬1000場比賽
選手A獲勝368場，佔比36.8%
選手B獲勝632場，佔比63.2%

體育競技測試用例

import Sports
print(Sports.simNGames(500,0.45,0.5))
print(Sports.simNGames(1000,0.5,0.45))
print(Sports.simNGames(5000,0.44,0.46))
print(Sports.gameOver(15,10))
print(Sports.gameOver(6,8))
print(Sports.gameOver(3,15))
print(Sports.simOneGame(0.45,0.5))
print(Sports.simOneGame(0.5,0.45))

批量安裝包

import os
libs ={"wordcloud","imageio"}
try:
    for lib in libs:
        os.system("pip install"+lib)
    print("successful")
except:
    print("false")
